ELECTRIC-LIGHT HANGER.

SPECIFICATION forming part Of Letters Patent N0. 623,363, dated April. 18, 1899.

Application filed Octobe 13, 1898. Serial No. 693,375. No model.) I

To (.tZZ whom it may concern.-

Be it known that we, WlLLIAM GIERTH and FREDERICK PETERS, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain newand useful Improvements in Electric-Light Hangers and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the. same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in suspending electric lamps such as are commonly hung over the street upon an arm projecting from a pole and are lowered and raised from time to time for cleaning and renewal of the carbons. Such lowering and raising has usually been done by means of a rope to the end of which the lamp is attached, said rope running through pulleys to a point convenient of access from the ground and always sustaining the full weight of the lamp. This is objectionable in that if the rope becomes weak or broken at any point the lamp will fall to the ground, entailing loss from breakage.

The objects of this invention are to provide means which shall support the lamp and carry its weightindependent of the rope when said lamp is in normal or elevated position, to provide such a device which will not interfere with or in any way impede raising and lowering the lamp by the rope as usual, to provide means for automatically catching and releasing the lamp, to do this without the use of levers or springs and by a construction simple and not liable to break or get out of order, and to secure other advantages and results some of which maybe referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved electric-light hanger and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

in which like letters of reference indicate- 'is a detail view of one of the sections of the suspending-link, and Fig. 6 is a side elevation showing the hanger in use in connection with a pole and lamp of ordinaryconstruction.

In said drawings, a indicates an arm which projects from the electric-light pole, as is common; 17, is the hanger-box or female member of the device; a, is the suspending-link or male member, adapted to enter at its upper end the hanger-box and be caught therein, and d is an electric lamp of any usual construction attached to the lower end of said suspending-link c. Said hanger box 1) is open at its bottom to admit the suspendinglink and at the top has a reduced extension Z), in which a pulley e for the rope his pivoted on a pin 6. Above the said pulley-chamber b is a horizontal integral sleevef, adapted to slide on the arm a and be secured in any desired position thereon by the set-screw f The suspending-link 0 comprises a body portion 0', preferably cylindrical and having an approximately "spherical upper end g and a flattened and perforated lowerend g. Said link is centrally and longitudinally-bored out from the spherical end g through the body portion 0 to the flattened end g, the tubular cavity thus formed serving to receive the end of the rope h.

To enable the end of the rope to be placed in the centrally-bored link, said link is made in two similar halves or sections Z Z, held firmly together by screws is it near each end, and being at the spherical end g, which is preferably hollow for the sake of lightness, provided with lugs Z Z, which prevent any lateral displacement or slipping of the sections upon one another. The inner or grooved surface of each section Zis provided with spurs j,those on one section preferably alternating in position with those on the other, said spurs being adapted to enter the rope h when the sections are forced together. The screw 76 at the spherical end of the link passes through the rope and further aids in firmly fastening said rope.

The lamp d is attached to the lower end of the suspending-link by means of a hook or wire passed through the perforation therein, and the rope h, secured at its end to said link, passes up through the hanger-box I), over the pulley e, and along the arm a in the usual manner.

Thehanger-box Z) is of slightly-greater thickness in a direction parallel to the arm a than the diameter of the spherical head g of the suspending-link, and upon the front and rear walls of the box are peculiarly-shaped rests n or, adapted to engage said spherical head in a manner to be more fully described. Said rests are each centrally disposed with reference to the width of the hanger-box I), thus lying vertically beneath the arm a, and each rest comprises a rib or ridge projecting from the wall a half-inch, more or less. This rib may be an d preferably is formed integral with the wall, from which it projects; but the rests may be separate pieces fastened to the wall in any suitable manner. The rib thus formed on the wall is approximately semicircular or crescent-shaped and is arranged on the wall in a tilted or oblique position, so that the rest has a hook shape in side view, as will be more clearly understood upon referring to Figs. 3 and 4 of the drawings. At all points of its length said rib projects the same distance from the wall of the hanger-box; but in a direction parallel to said wall the rib is thicker at or near its middle part and tapers toward each end to form arms 19 q, convexly curved outward. The said thickened middle portion of the rib is on the convex side of the rib brought to a point 0, at which point the convexly-curved outer sides of the arms meet. Said point 0 lies at or near the lower edge of the hanger-box at one side of the verticalline passing through the supporting-arm a, and the arms 1) q of the rest extend obliquely upward across the said vertical line, the upper arm p being longer than the lower q. The inner sides of the arms 1) q are concavely curved at a greater degree of curvature than the outer sides and are rounded together where they meet to form a seat or recess '1", adapted to fit the spherical head g of the suspending-link. The position of said rests is such that the center of said spherical head as it lies in the recess 0 will be vertically beneath the supporting-arm a, as will be understood.

In drawing the lamp up to its place by means of the rope h the head of the hanger strikes the inclined outer sides of the lower arms q q of the rests n n and is thereby forced to one side until it passes the extremities q of said arms. Then gravity causes the lamp to swing back into a vertical line, throwing the head g into the recess 1' of the rests fitted to receive it, and thus the lamp is supported independent of the rope h, as will be understood.

To lower the lamp, the rope is drawn upon, and this lifts the head g from the recess 0* into contact with the inner sides of the upperarms p 19, whereby it is guided laterally outward to pass around the ends pp' of said arms, when gravity again brings the lamp and its rope into a vertical line. Now if theropeis slackened the head Q will strike the inclined outer sides of the arms 1) p and be guided thereby entirely past the rests n n on the opposite side from that on which it was drawn up and the lamp may be lowered as usual.

The hanger-box bis made of sufficient width to allow the head 9 to pass either side of the restsn 92, between said rests and the sides of the box.

One wall of the hanger-box, preferably the front one, as t, is cast in a separate piece, so as to serve as a door or cover permitting access to the interior, said cover being fastened in place by lugss and screws 5'. Strengthening-ribs i may be cast upon said removable cover t. ears 7) o are provided at opposite sides of the hanger-box, which may serve as means for attaching guy ropes or wires 'v' Q), running to the main pole and steadying the hanger and arm a against oscillation. \Ve also prefer to form on the top of the sleeve f upwardly-projecting parallel lugs w 10, providing a space between adapted to receive the end of a rigid rod orbrace m, if desired, said end being perforated and secured in place by a pin t and the rod m, extending upward to the pole from which the arm a projects.

Other modifications of minor details may be made without departing from the spirit and scope of the invention, and we do not wish to be limited by the positive terms employed in the foregoing description excepting as the state of the art may require.

Having thus described the invention, what we claimas new'is- 1.
